Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The instant disclosure relates to a sunshade device having a
plurality of operable frames and operable blades; in particular, to
a multi-stage sunshade device.
[0003] 2. Description of Related Art
[0004] Ventilation and lighting in modern architecture typically
provides windows in almost every room, especially glass curtain
walls that provide views overlooking the outdoor landscape. When
sunlight is rather intense, such window designs are likely to rise
the indoor temperature that can cause discomfort or compromise
privacy among occupants, making blinds the prevalent choice to be
installed on windows in order to shield sunshine or provide
privacy.
[0005] However, current blinds are limited to only a few choices
that provide either complete coverage or angle adjustments of blind
blades that control the amount of incident light, yet still cannot
meet all application demands.
[0006] To address the above issues, the inventor strives via
associated experience and research to present the instant
disclosure, which can effectively improve the limitation described
above.
SUMMARY OF THE INVENTION
[0007] The objective of the instant disclosure is to provide a
multi-stage sunshade device to resolve the issue above.
[0008] In order to achieve the aforementioned objectives, according
to an embodiment of the instant disclosure, a multi-stage sunshade
device is provided. The multi-stage sunshade device includes two
fixed frames, two first operable frames, two second operable
frames, a plurality of first operable blades, a first linked
module, a plurality of second operable blades, and a second linked
module. The two fixed frames are arranged to face one another to
define a main window plane, and each fixed frame has a guiding
rail. The two first operable frames are arranged to face one
another to define a first window plane, each first operable frame
has two ends defined as a first guiding end and a first pivotable
end, and two of the first guiding ends are pivotably connected into
the guiding rails of the two fixed frames. The two second operable
frames are arranged to face one another to define a second window
plane, each second operable frame has two ends defined as a second
pivotable end and a first guiding end, two of the second pivotable
ends are pivotably connected to two of the first pivotable ends,
and two of the guiding ends are pivotably connected into the
guiding rails of the two fixed frames. Each first operable blade
has two ends respectively and pivotably connected to two first
operable frames. The first linked module is connected to the
plurality of first operable blades and synchronously rotates with
the plurality of first operable blades in identical directions so
that the first operable blades can selectively cover the first
window plane. Each second operable blade has two ends respectively
and pivotably connected to two second operable frames. The second
linked module is connected to the plurality of second operable
blades and synchronously rotates with the plurality of second
operable blades in identical directions so that the second operable
blades can selectively cover the second window plane. Two first
guiding ends and two corresponding second guiding ends can be
proximate or distal to one another along the two guiding rails, so
that the first operable blades and second operable blades of the
first operable frame and second operable frame can selectively
cover the main window plane.
[0009] The instant disclosure provides the following improvements.
The operable blades can selectively cover the first window plane
according to the user's needs, while the second operable blades can
still selectively cover the second window plane as needed, whereas
the first operable frames and the second operable frames can
selectively move with respect to the two fixed frames as needed.
With the flexible operability of the first and second operable
blades in conjunction with the first and second operable frames,
multiple modes of sun shading can be provided.
[0010] In order to further understand the instant disclosure, the
following embodiments and illustrations are provided. However, the
detailed description and drawings are merely illustrative of the
disclosure, rather than limiting the scope being defined by the
appended claims and equivalents thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] The aforementioned illustrations and detailed descriptions
are exemplarity for the purpose of further explaining the scope of
the instant disclosure. Other objectives and advantages related to
the instant disclosure will be illustrated in the subsequent
descriptions and appended drawings.
[0019] Please refer to FIGS. 1 and 2 which are exploded and
assembled views of the multi-stage sunshade device in accordance
with the instant disclosure. The multi-stage sunshade device 1
includes two fixed frames 10, two first operable frames 20, two
second operable frames 30, a plurality of first operable blades 21,
a first linked module 22, a plurality of second operable blades 31,
and a second linked module 32. Two fixed frames 10 are arranged to
face one another to define a main window plane (Y-Z plane of the
axis as shown in FIG. 2). Each fixed frame 10 has a guiding rail
101. The guiding rail 101 can be of any shape or form, such as a
linear guiding rail, a through opening as shown in the figures, or
in a similar manner.
[0020] Two first operable frames 20 are arranged to face one
another to define a first window plane (not labeled). Each first
operable frame 20 has two ends, in which the two ends are defined
as a first guiding end 201 and a first pivotable end 202. Two first
guiding ends 201 of the two first operable frames 20 are pivotably
arranged and moved in the guiding rails 101 of the two fixed frames
10.
[0021] Two second operable frames 30 are arranged to face one
another to define a second window plane (not labeled). Each second
operable frame 30 has two ends, in which two ends are defined as a
second guiding end 301 and a second pivotable end 302. Two second
guiding ends 301 of the two second operable frames 30 are pivotably
arranged and moved in the guiding rails 101 of the two fixed frames
10. The two second pivotable ends 302 of the two second operable
frames 30 are pivotably connected to two first pivotable ends 202
of the two first operable frames 20. Each of the first guiding ends
201 and each of the second guiding ends 301 are pivotably connected
in the guiding rail 101 via a supplementary guiding member 204,
such as rollers, linear sliding blocks, etc. Two first pivotable
ends 202 can be pivotably connected to two second pivotable ends
302 via two supplementary pivoting members 203, but the invention
is not limited hereto.
[0022] In other words, after two first operable frames 20 and two
second operable frames 30 are mutually and pivotally connected,
another side of each first operable frame 20 and another side of
each second operable frame 30 not mutually connected (the first
guiding end 201 and the second guiding end 301) are respectively
and pivotably connected to the two fixed frames 10. As a result,
two first guiding ends 201 can be proximate to or distal to the
corresponding two second guiding ends 301 within the two guiding
rails 101. Moreover, the two first operable frames 20 and two
second operable frames 20 that are coupled to one another can
selectively change the angle between the first window plane and the
second window plane.
[0023] Specifically, as shown in FIGS. 3 and 4, when two first
guiding ends 201 of the two first operable frames 20 are fixed at
one end of the fixed frame 10, two second guiding ends 301 (please
refer to FIG. 1) of two operable frames 30 can move along the
guiding rail 101 towards a first movable direction V1 or a second
movable direction V2 to change the angle between the connected
second operable frame 30 and the first operable frame 20. When two
first guiding ends 201 and the two second guiding ends 301 are
arranged on separate ends of the two guiding rails 101, two first
operable frames 20 and two second operable frame 30 are
respectively adjusted to an angle of about 180 therebetween. When
the two first guiding ends 201 and the two second guiding ends 301
are arranged closest to one another on the guiding rail 101, two
first operable frames 20 and two second operable frames 30 are
respectively adjusted to an acute angle therebetween.
[0024] Two ends of the first operable blades 21 can be respectively
coupled to the corresponding inner sides of two first operable
frames 20. The first linked module 22 can be connected to the first
operable blades 21, so that the first operable blades 21 can
synchronously rotate towards the same direction, and the first
operable blades 21 can selectively cover the first window plane.
Similarly, two ends of the first operable blades 21 can be
respectively coupled to the corresponding inner sides of two second
operable frames 30. The second linked module 32 can be connected to
the second operable blades 31, so that the second operable blades
31 can synchronously rotate towards the same direction, and the
second operable blades 31 can selectively cover the second window
plane.
[0025] Specifically, the first linked module 22 can have a first
linkage 221 and a first driving unit 222. The first linkage 221 can
be movably arranged at the inner side of one of the first operable
frames 20. A side of the first linkage 221 facing another first
operable frame 20 is pivotally connected to one end of each of the
first operable blades 21. One end of the first linkage 221 and the
first driving unit 222 are pivotally connected, and the first
linkage 221 can be driven by the first driving unit 222 to move at
the inner side of the first operable frame 20. Namely, when the
first driving unit 222 is driven to rotate, the first linkage 221
can be driven to move at the inner side of the first operable frame
20, so that the first operable blades 21 are also driven to
synchronously rotate in the same direction and selectively cover
the first window plane. The second linked module 32 can also have a
second linkage 321 and a second driving unit 322. Two ends of the
second operable blades 31 can be respectively coupled to the
corresponding inner sides of two second operable frames 30 and the
corresponding inner sides of two linkages 321. With the second
linkage 321 driven to move by the second driving unit 322, the
second operable blades 31 can rotate towards the same direction,
and the second operable blades 31 can selectively cover the second
window plane.
[0026] As shown in FIGS. 5 and 6, when the first driving unit 222
is driven to rotate in a first rotational direction L1, the first
linkage 221 is also driven to move, so that the first operable
blades 21 synchronously rotate from the mode as shown in FIG. 5 to
a mode as shown in FIG. 6. On the contrary, when the first driving
unit 222 rotates in a second rotational direction L2, the first
linkage 221 is also driven to move, so that the first operable
blades 21 synchronously rotate from the mode as shown in FIG. 6 to
the mode as shown in FIG. 5.
[0027] In application, the first linked module 22 and the second
linked module 32 can be mechanically connected to one another. For
example, an additional driving unit (not shown) can be arranged on
two separate first pivotable ends 202. The first linkage 221 and
the second linkage 321 are connected to one another via the driving
unit, so that the first operable blades 21 and the second operable
blades 31 can synchronously rotate in the same direction by
adjusting the first driving unit 222 or the second driving unit
322.
[0028] Please refer to FIG. 7 (please refer to FIG. 1 for elements
and components not labeled in FIG. 7 for the descriptions
hereafter). In the preferred embodiment, the multi-stage sunshade
device 1 can include a driving device 40 that is mechanically
connected to at least one first guiding end 201 or at least one
second guiding end 301 in order to drive together or apart the two
first guiding ends 201 and two second guiding ends 301.
Specifically, the driving device 40 can be mechanically connected
to the first guiding end 201 or the second guiding end 301 via the
supplementary guiding member 204, such that the first guiding end
201 and the second guiding end 301 are mutually closer or away from
each other via controlling the supplementary guiding member 204. As
a result, a user can modify the surface area of the main window
plane being covered via modifications to the positions of the first
operable frame 20 and the second operable frame 30 with respect to
the fixed frame 10.
[0029] Specifically, when the first window plane is covered with
the first operable blades 21 and the second window plane is covered
with the second operable blades 31, the user can change the
relative positions of the first operable frame 20, the second
operable frame 30, and the fixed frame 10 via the control of the
driving device 40, so the state in which the main window plane is
being covered can be modified as required by the user. For example,
when the distance between the first guiding ends 201 and the second
guiding ends 301 is at its largest, users can choose to cover the
main window plane completely or partially in intervals with
adjustments made to the positions of the first operable blades 21
and the second operable blades 31. When the distance between first
guiding ends 201 and the second guiding ends 301 is at its
smallest, a large portion of the main window plane is not covered
by the first operable frames 20, the first operable blades 21, the
second operable frames 30, and the second operable blades 31.
[0030] In the preferred embodiment, the driving device 40 is not
only mechanically connected to the first guiding ends 201 or the
second guiding ends 301, the driving device 40 can also be
mechanically connected to the first linked module 22 and the second
linked module 32. Consequently, a user can simultaneously control
the first operable frame 20, the second operable frame 30, the
first linked module 22, and the second linked module 32 to provide
various modes of coverage. Moreover, the user can also separately
control the first operable frame 20, the second operable frame 30,
the first linked module 22, and the second linked module 32 to
further accommodate the users' needs. For example, the driving
device 40 can control the first linked module 22 and the second
linked module when the distance between two first guiding ends 201
and the corresponding two second guiding ends 301 are closest to
one another, so that the first operable blades 21 and the second
operable blades 31 demonstrate a mode that covers the first window
plane and the second window plane, which facilitates the two first
operable frames 20 and the two second operable frames 30 to
collapse to the smallest possible volume.
[0031] Notably, the first operable frame 20 and the second operable
frame 30 can be made from relatively strong materials that can
withstand a locking device to be disposed over the first operable
frame 20, the second operable frame 30, and the fixed frame 10. The
multi-stage sunshade device of the instant disclosure not only
provides multiple sun-shading or covering modes as needed to
completely cover the main window plane with the first operable
frame 20 and the second operable plane 30, but also provides
security along with the locking device that optionally locks
together the operable frames with the fixed frame 10.
[0032] The figures and descriptions supra set forth illustrate the
preferred embodiments of the instant disclosure; however, the
characteristics of the instant disclosure are by no means
restricted thereto. All changes, alterations, combinations or
modifications conveniently considered by those skilled in the art
are deemed to be encompassed within the scope of the instant
disclosure delineated by the following claims.
